Correct gmock/gtest expectations w.r.t. C++11/RTTI

Long story short, some of the tests were failing because they expected either
dynamic_cast or RTTI to be functional and it wasn't.

Move all common CXXFLAGS out to googletest.test.inc.mk and reference it from
googletest.test.mk and .../googletest/Makefile.inc
